RESUMEN
OBJECTIVES: To observe the effect of catgut embedding at "Feishu"(BL13), "Dingchuan" (EX-B1) and "Danzhong" (CV17) on expression of phosphorylated p38 mitogen activated protein kinase (p-p38 MAPK), interleukin-4 (IL-4), interferon-γ (IFN-γ) and changes of airway epithelial cells (AEC) in the lung tissue of bronchial asthma (BA) rats, so as to explore its mechanisms underlying improvement of BA. METHODS: Forty male Wistar rats were randomly and equally divided into blank control, model, dexamethasone (DEX) and catgut embedding groups. The BA model was established by intraperitoneal injection of suspension of ovalbumin and aluminum hydroxide. Rats of the DEX group received intraperitoneal injection of DEX (1.5 mg/kg), once daily for 2 weeks, and those of the catgut embedding group received catgut embedding at BL13, EX-B1 and CV17 only one time. The rats' sneezing times per miniute in each group were recorded. H.E. staining was used to observe the histopathological changes of the lung tissue under light microscope. A transmission electron microscope (TEM) was used to observe the ultrastructural changes of AEC in the lung tissue, including the thickness of bronchial wall and bronchial smooth muscle by using an image analysis software. The protein expressions of p-p38 MAPK, IL-4 and INF-γ in the lung tissue were determined using Western blot. RESULTS: Morphological observation revealed that in the model group, light microscope showed deformed and swollen bronchial tube wall with increased folds and thickened bronchial smooth muscleï¼and TEM showed a large number of autophagy vesicles containing swollen and deformed organelles in the AEC, and apparent reduction of intracellular mitochondria, these situations were obviously milder in both DEX and catgut embedding groups. Compared with the blank control group, the sneezing times, thickness of bronchial wall and bronchial smooth muscle in the model group were significantly increased (P<0.01), and the expressions of p-p38 MAPK and IL-4 in lung tissue were significantly increased (P<0.01), while the expression of IFN-γ was significantly decreased (P<0.01) in the model group. In comparison with the model group, the sneezing times, thickness of bronchial wall and bronchial smooth muscle, protein expressions of p-p38 MAPK and IL-4 were significantly decreased (P<0.01), while the expression of IFN-γ was obviously increased (P<0.01) in both the DEX and catgut embedding groups. CONCLUSIONS: Acupoint catgut embedding can reduce the expression of IL-4 and increase the expression of IFN-γ by inhibiting p38 MAPK signal pathway of lung tissues in BA rats, which may contribute to its effect in alleviating the degree of airway epithelial cells damage.

Objective: The efficacy of acupoint catgut embedding (ACE) for the treatment of pre-diabetes remains controversial. Therefore, this study investigated the clinical efficacy and acupoint selection in ACE for the treatment of pre-diabetes. Methods: Eight common databases were searched for relevant literature on ACE for pre-diabetes. Meta-analysis was used to evaluate its efficacy and safety, and data mining was used to explore the protocol for acupoint selection. Results: The meta-analysis revealed that compared with conventional treatment alone, conventional treatment combined with ACE reduced the levels of glycated hemoglobin A1c [mean difference (MD) -0.45, 95% confidence interval (CI) -0.67 to -0.24%, p < 0.001], fasting blood glucose (MD -0.61 mmol/L, 95% CI -0.87 to -0.36 mmol/L, p < 0.001), 2-h postprandial glucose (MD -0.77 mmol/L, 95% CI -0.98 to -0.55 mmol/L, p < 0.001), total cholesterol (MD -0.37 mmol/L, 95% CI -0.74 to 0.00 mmol/L, p = 0.049), triglyceride (MD -0.49 mmol/L, 95% CI -0.77 to -0.20 mmol/L, p < 0.001) and low-density lipoprotein cholesterol (MD -0.23 mmol/L, 95% CI -0.33 to -0.12 mmol/L, p < 0.001), and increased high-density lipoprotein cholesterol levels (MD 0.16 mmol/L, 95% CI 0.05 to 0.27 mmol/L, p = 0.004), whereas changes in the body mass index and the adverse event rates were comparable between groups. Data mining revealed that Pishu (BL20), Weiwanxiashu (EX-B3), Zusanli (ST36), Shenshu (BL23), Sanyinjiao (SP6), Weishu (BL21), and Taixi (KI3) were the core acupoints used in ACE for pre-diabetes. Conclusion: ACE can effectively improve blood glucose and lipid levels in pre-diabetes patients and has a good safety profile. ACE consisting of Pishu (BL20), Weiwanxiashu (EX-B3), Zusanli (ST36), Shenshu (BL23), Sanyinjiao (SP6), Weishu (BL21), and Taixi (KI3), is a promising complementary strategy for the treatment of pre-diabetes.

Electroacupuncture (EA) or acupoint catgut embedding (ACE) plays a therapeutic role in functional dyspepsia (FD). Herein, we aimed to elucidate the influences of EA combined with ACE on gastrointestinal motility and gastrointestinal hormones in rats with FD. Sprague-Dawley rats were randomized into the control group, model group, EA group, ACE group, and EA + ACE group (n = 10). Except for the control group, the rats in all groups were modeled by combining neonatal iodoacetamide gastrogavage and modified tail-clamping stimulation. The rats were treated with different treatments according to their groups. The rats were observed for changes in general behavior, body weight, food intake, and paw mechanical pain threshold. Gastric emptying rate (GER) and intestinal propulsive ratio (IPR) were measured in each group, and serum gastrointestinal hormone (motilin [MTL], leptin, gastrin [GAS], vasoactive intestinal peptide [VIP], calcitonin gene-related peptide [CGRP], and somatostatin [SS]) levels, oxidative stress factors (superoxide dismutase [SOD] and malondialdehyde [MDA]) and 5-hydroxytryptamine (5-HT) levels were also measured. Decreased mean body weight, paw mechanical pain thresholds, food intake, and GER and IPR were found in rats of the model group in comparison to the control group. Serum MTL, GAS, SS, and SOD levels were reduced, and serum leptin, VIP, CGRP, MDA, and 5-HT levels were increased in rats of the model group in comparison to the control group. Elevated mean body weight, paw mechanical pain threshold, food intake, GER and IPR, and serum MTL, GAS, SS, and SOD levels, and reduced serum leptin, VIP, CGRP, MDA, and 5-HT levels were observed in rats of the EA, ACE, and EA + ACE groups relative to the model group. EA combined with ACE treatment was more effective than the EA or ACE treatment alone. EA combined with ACE treatment improves gastrointestinal motility and gastrointestinal hormone levels, promotes food intake, and reduces visceral hypersensitivity in FD rats.

OBJECTIVE: To assess the efficacy of acupoint catgut embedding (ACE) for simple obesity in preclinical animal experiments. METHODS: We searched the following 14 electronic databases: PubMed, Cochrane Library, EMBASE, Oriental Medicine Advanced Searching Integrated System, KoreaMed, Korean Studies Information Service System, Science-on, Research Information Sharing Service, Korea Citation Index, Korea Traditional Knowledge Portal, China Network Knowledge Infrastructure Database, Wanfang Database, Chinese Science and Technology Journal Database, and Chinese Biology Medicine Database, from inception to November 2021 without language limitation. The assessment was performed according to the guidelines of Animal Research: Reporting of experiments; and Meta-analysis was performed using Reviewer Manager 5.4.1 software. RESULTS: Twenty-four studies involving 813 animals were selected. Meta-analysis showed that ACE was beneficial for weight control [ 40, = -50.63, 95% (ï¼57.59, ï¼43.67), 0.000 01, = 0%] and reduced the Lee index [ 40, = ï¼18.79, 95% (ï¼20.01, ï¼17.57), 0.000 01, = 0%]. However, when efficacy of ACE was compared with that of manual acupuncture, electroacupuncture, or oilistat therapy, statistical difference was not observed between the two groups. CONCLUSIONS: This systematic review suggests that ACE may be efficacious in treating obesity. Moreover, the analyses highlighted the necessity to perform well-designed, higher-quality experiments.

OBJECTIVE: To investigate the effects of acupoint catgut embedding for 3 weeks on lung tissue, blood immunoglobulin E (IgE) and interleutin-4 (IL-4), brain tissue microglia x-42 (OX-42) and toll-like receptor-2 (TLR-2) in rats with allergic rhinitis of lung deficiency type. METHODS: Forty-five female Sprague-Dawley rats were randomly divided for two times. The first time, they were randomly divided into model group and blank group (Group C) according to 2:1, and the second time, the model group were randomly divided into model control group (Group B) and intervention treatment group (Group A) according to 1:1. 15 in each group. For Group A and Group B, the lung deficiency model was made by "sulfur-moxa fumigation", and then the allergic rhinitis model was established by "ovalbumin (OVA) sensitization". Then catgut embedding was performed at acupoints in Group A and not in Group B. After 3 weeks, collect lung tissue samples for hematoxylin-eosin staining, then take blood to observe the concentration of IgE and IL-4, and finally take brain tissue to observe the results of OX-42 and TLR-2. RESULTS: IgE level (µg/mL) was (3.11 ± 0.20) in the Group A, (4.19 ± 0.44) in the Group B, and (2.29 ± 0.30) in the Group C (all < 0.001). IL-4 level (pg/mL) was (14.2 ± 0.7) in the Group A, (18.6 ± 2.4) in the Group B, and (11.4 ± 1.2) for the Group C (all < 0.001). The mean OD for OX-42 is (0.1728 ± 0.0016) in the Group A, (0.1810 ± 0.0046) in the Group B and (0.1674 ± 0.0025) in the Group C (all < 0.001). CONCLUSION: Although 3 weeks of acupoint catgut embedding already showed obvious efficacy on rats with allergic rhinitis, the allergic reaction in the body still continued. To achieve further treatment, prolonging the catgut embedding time is necessary.

OBJECTIVE: To observe the effects of catgut embedding and polyglycolic acid/poly-lactic acid (PGLA) embedding at "Zusanli" (ST 36) on the activation of local skin mast cells (MC), and expression of substance P (SP) and histamine (HA), and to explore the mechanism of the temporal stimulation effect of acupoint catgut embedding and provide a foundation for further research on the initiation mechanism of acupoint catgut embedding. METHODS: One hundred and sixty male SPF-grade SD rats were randomly divided into a blank group (10 rats), a sham-embedding group (50 rats), a catgut group (50 rats), and a PGLA group (50 rats). Each intervention group was further randomly divided into five subgroups according to the time points after intervention: 8 hours, 3 days, 7 days, 14 days, and 21 days, with 10 rats in each subgroup. One-time sham-embedding, catgut embedding and PGLA embedding was given at left "Zusanli" (ST 36) in each intervention group, respectively. The skin and subcutaneous connective tissue of the left "Zusanli" (ST 36) were collected at the corresponding time points after intervention, except for the blank group (only one day before intervention). Toluidine blue staining was used to detect MC count and degranulation, and immunohistochemical staining was used to detect the expression of SP and HA positive cells. RESULTS: There was no significant difference in MC count between the subgroups of each intervention group and the blank group (P>0.05). There was no significant difference in MC count between the subgroups of the catgut group and the PGLA group (P>0.05). The MC count in the 8-hour subgroup of PGLA group was higher than that in the 8-hour subgroup of catgut group (P<0.05), while the MC count in the 21-day subgroup of PGLA group was lower than that in the 21-day subgroup of catgut group (P<0.05). Compared with the blank group, the degranulation rates of MC were increased in the 8-hour and 3-day subgroups of sham-embedding group, 8-hour, 3-day, and 7-day subgroups of catgut group, and 8-hour, 3-day, 7-day, and 14-day subgroups of PGLA group (P<0.01, P<0.05, P<0.001). There was no significant difference in the degranulation rate of MC between the subgroups of the catgut group and the PGLA group (P>0.05), and no significant difference in the degranulation rate of MC between the two embedding groups at the same time point (P>0.05). Compared with the blank group, the expression of SP positive cells was increased in the 8-hour subgroup of sham-embedding group, 8-hour, 3-day, 7-day, and 14-day subgroups of catgut group, and 3-day, 7-day, and 14-day subgroups of PGLA group (P<0.001, P<0.05). The expression of SP positive cells in the 7-day subgroup of catgut group was higher than that in the 8-hour subgroup of catgut group (P<0.05), while the expression of SP positive cells in the 14-day subgroup of catgut group was lower than that in the 7-day subgroup of catgut group (P<0.001). The expression of SP positive cells in the 7-day subgroup of PGLA group was higher than that in the 3-day subgroup of PGLA group (P<0.05), while the expression of SP positive cells in the 14-day subgroup of PGLA group was lower than that in the 7-day subgroup of PGLA group (P<0.01). There was no significant difference in the expression of SP positive cells between the subgroups of the two embedding groups at the same time point (P>0.05). Compared with the blank group, the expression of HA positive cells was increased in the 8-hour, 3-day subgroups of sham-embedding group, 8-hour, 3-day, 7-day, and 14-day subgroups of catgut group, and 8-hour, 3-day, 7-day, 14-day, and 21-day subgroups of PGLA group (P<0.001, P<0.01, P<0.05). The expression of HA positive cells in the 14-day subgroup of catgut group was lower than that in the 7-day subgroup of catgut group (P<0.05), while the expression of HA positive cells in the 3-day subgroup of PGLA group was higher than that in the 8-hour subgroup of PGLA group (P<0.05), and the expression of HA positive cells in the 14-day subgroup of PGLA group was lower than that in the 7-day subgroup of PGLA group (P<0.05). The expression of HA positive cells in the 3-day subgroup of PGLA group was higher than that in the 3-day subgroup of catgut group (P<0.05). CONCLUSION: Catgut and PGLA embedding at "Zusanli" (ST 36) in healthy rats could induce changes in local skin MC, SP, and HA, which may be one of the mechanisms of the temporal stimulation effect after acupoint embedding. There are certain differences between different suture materials. A moderate inflammatory response in the acupoint area, mediated by MC and involving SP and HA, may be one of the initiating factors for the effect of acupoint catgut embedding.

OBJECTIVE: To explore the difference of catgut embedding effect between acupoints and non-acupoints in patients with abdominal obesity (AO). METHODS: In this multicenter, double-blind, randomized controlled trial, all subjects were randomly assigned into the acupoint catgut embedding (ACE) group and control group (catgut embedding at non-acupoints). With a 12-week actual intervention period and a 4-week period of follow-up. Waist circumference (WC), body weight, body mass index (BMI), hip circumference (HC) and appetite were applied and assessed at baseline and after 6, 12 and 16 weeks. RESULTS: After the total intervention phase (12 weeks), the WC, body weight, BMI, HC and visual analogue scale scores of appetite, decreased significantly in the two groups as compared to the baseline (0.001). Meanwhile, after the 4-week follow-up, the indicators still decreased significantly in the ACE group (0.001). At 12 and 16 weeks, catgut embedding at acupoints showed significantly advantages to non-acupoints in WC and appetite (0.05). No serious adverse events were observed in ACE group and control group. CONCLUSIONS: Catgut embedding at acupoints and non-acupoints are all effective and safe for AO. ACE can effectively treat AO as expected and deliver lasting results.

BACKGROUND: Obesity is an increasing problem worldwide. The effective treatments for obesity mainly include diet, physical activity, behavioral intervention, pharmacotherapy, and bariatric surgery, which all have certain limitations. As a specific type of acupuncture therapy, acupoint catgut embedding (ACE) has gained substantial attention in the management of obesity in recent years. Previous studies suggested that ACE may be an effective obesity treatment. However, the evidence for the efficacy of ACE in abdominal obesity (AO) remains inadequate due to the paucity of high-quality studies. OBJECTIVE: This study aims to investigate the difference in the effectiveness of catgut embedding at acupoints and catgut embedding at nonacupoints in patients with AO and to further validate the efficacy and safety of ACE for AO. METHODS: This is a multicenter, double-blind, 16-week randomized controlled trial. A total of 92 eligible participants with AO will be randomly divided into 2 groups (1:1 allocation ratio). The ACE group will receive catgut embedding at acupoints and the control group will receive catgut embedding at nonacupoints. The intervention will be performed every 2 weeks for a total of 6 sessions. Follow-up will be performed every 2 weeks for a total of 2 visits. The primary outcome is waist circumference. Secondary outcomes include body weight, BMI, hip circumference, and the visual analog scale of appetite. Upon the completion of the trial, we will evaluate the effect of catgut embedding at acupoints or nonacupoints on obesity indicators in patients with AO. For treatment outcomes, an intention-to-treat analysis will be performed. RESULTS: The start of recruitment began in August 2019 and is expected to end in September 2023. CONCLUSIONS: Although studies have been conducted to demonstrate the effectiveness of ACE in the treatment of obesity, the evidence for the efficacy of ACE in AO remains insufficient due to the quality of the studies. This rigorous normative randomized controlled trial will verify the effect of catgut embedding at acupoints or nonacupoints in patients with AO. The findings will provide credible evidence as to whether ACE is an effective and safe treatment for AO.

RESUMEN
OBJECTIVE: To observe the effect of acupoint catgut embedding (CE) on Nod-like receptor protein 3 (NLRP3)/Caspase-1 signaling pathway in "deficiency-stasis" syndrome type ulcerative colitis (UC) rats, so as to explore its mechanisms underlying improvement of UC. METHODS: A total of 58 male SD rats were randomly divided into control group (10 rats) and model group (48 rats). The "deficiency-stasis" type UC model was established by gavage of adenine and folium sennae solution for 4 weeks, followed by clycter of mixture solution of 5% trinitro-benzene-sulfonic acid and 50% ethanol. A total of 44 UC rats were randomized into model, salicylazosulfapyridine (SASP), non-acupoint CE, and acupoint CE groups (11 rats in each group). The catgut embedment was applied to bilateral "Zusanli"(ST36), "Shenshu"(BL23), "Pishu"(BL20), "Dachangshu"(BL25), "Geshu" (BL17) and "Tianshu"(ST25), or non-acupoints (the fat muscles of the buttocks), separately, once every two weeks, 3 times altogether. Rats of the SASP group received gavage of SASP solution, and those of the other groups received gavage of same amount of normal saline, once daily for 42 days. The rat's general conditions and the colon length were recorded, the disease activity index (DAI, 0 to 4 points) and colonic mucosal damage index (CMDI, 0 to 5 points) were calculated. Histopathological changes of the colonic mucosa tissue were observed after HE staining, and the tissue damage index (TDI, 0 to 6 points) was given. The levels of serum NLRP3, interleukin (IL)-1ß and IL-18 were measured by ELISA, and the expression levels of NLRP3, Caspase-1, apoptosis-associated speck-like protein (ASC), IL-1ß and IL-18 mRNAs were measured by fluorescence quantitative PCR. The expression levels of NLRP3 and Caspase-1 proteins in the colon tissues were measured by Western blot, and the immunoactivity of colonic ASC was detected by immunohistochemistry. RESULTS: Compared with the control group, the rats' body mass and colonic length were significantly decreased (P<0.01), and DAI score, CMDI score, TDI score, contents of serum NLRP3, IL-1ß and IL-18, expression levels of colonic NLRP3, ASC, Caspase-1, IL-1ß and IL-18 mRNAs, and NLRP3 and Caspase -1 proteins as well as colonic ASC immunoactivity were significantly up-regulated in the model group (P<0.01). Compared with the model group, both SASP and acupoint CE groups had a significant increase in body mass and colonic length (P<0.01), and a marked decrease in DAI score, CMDI score, TDI score, contents of serum NLRP3, IL-1ß and IL-18, expression levels of NLRP3, ASC, Caspase-1, IL-1ß and IL-18 mRNAs and NLRP3 and Caspase-1 proteins and ASC immunoactivity (P<0.01). The above indexes were improved in the acupoint CE group in relevant to those of the non-acupoint CE group (P<0.01). HE staining of colonic mucosal tissue showed obvious ulcerative surface, destroyed recess, disordered arrangement of glands, mucosal edema and congestion, infiltration of a large number of inflammatory cells in the model group, which was obviously milder in both SASP and acupoint CE groups. CONCLUSION: Acupoint embedding can alleviate colonic injury and inhibit inflammatory reaction in rats with "deficiency-stasis" type UC by down-regulating colonic NLRP3/Caspase-1 signaling.

BACKGROUND: Chronic pain refers to pain that persists for over three months. Chronic pain may restrict activities of daily living, including work, learning, social life, and can lead to anxiety, depression, and sleep disturbance. Imaging data have demonstrated that central sensitization often occurs in the brain of patients with chronic pain, which arises from imbalanced neurotransmission in the central nervous system. Transient receptor potential vanilloid 1 (TRPV1) is an ion channel to serve as an inflammatory detector in the brain. We aim to determine the properties of acupoint catgut embedding (ACE) on cold stress-induced mice fibromyalgia (FM) and surveyed the character of TRPV1 and linked molecules in chronic FM pain. METHODS: Intermittent cold stress (ICS) was used to induce mice FM model. Mice were subgrouped into normal mice, ICS-induced FM group, FM mice with ACE, and FM in Trpv1-â£/- group. ACE is a novel acupuncture technique that provides convenience and continuous nerve stimulation that has been reported effective on pain management. RESULTS: Our behavioral experiments showed similar levels of pain response among all groups before treatment. After ICS, prolonged mechanical and thermal pain was initiated (mechanical threshold: 1.96 ± 0.12 g; thermal latency: 4.86 ± 0.21 s) and were alleviated by ACE treatment and TRPV1 gene deletion. Inflammatory mediators were increased in the plasma of FM mice, while TRPV1 and related kinases were amplified in the hypothalamus and cerebellum. These changes were ameliorated in the ACE-treated and Trpv1-â£/- groups. CONCLUSIONS: These novel findings suggest that chronic FM pain can be modulated by ACE or TRPV1 gene deletion. The analgesic effect of ACE through the TRPV1 pathway may reflect its potential as a therapeutic target for FM treatment.

Chronic non-specific low back pain (CNLBP) is one of the leading causes of disability worldwide. Acupoint embedding (ACE) is widely used in China for the treatment of chronic non-specific low back pain, but there are no rigorous randomized controlled trials (RCTs) to confirm the effectiveness and safety of ACE for chronic non-specific low back pain. In this study, we design a single-center, single-blind, prospective RCT, with the aim of evaluating the efficacy and safety of ACE for CNLBP. 82 participants with CNLBP will be randomized in a 1:1 ratio into an ACE group and a sham ACE group. Participants will receive either ACE treatment or sham ACE treatment at once every 2 weeks, for an 8-week period, and followed by 6 months of follow-up. The primary outcome will be the change in visual analog scale (VAS) scores before and after treatment. Secondary outcomes will include the Oswestry Disability Index (ODI), the Roland Morris Disability Questionnaire (RMDQ) and the Short Form 36-Health Survey (SF-36). Adverse events that occur during the course of the trial will be recorded. Data will be analyzed according to a predefined statistical analysis plan. This study was approved by the medical ethics committee of Guangzhou Panyu Hospital of Chinese Medicine (202230). Written informed consent from patients is required. This trial is registered in the Chinese Clinical Trial Registry (ChiCTR2200059245). Trial results will be published in a peer-reviewed academic journal.

RESUMEN
Background: Depression is a common public health problem, characterized by persistent low mood, lack of pleasure and exhaustion. Conventional treatments such as antidepressants and psychotherapy have some limitations, including variable efficacy, adverse side effects and high costs. Acupoint catgut embedding (ACE) therapy, as a subtype of acupuncture, has gained increasing clinical application due to its long-term effects, higher patient compliance, and cost-effectiveness. This study aims to conduct a meta-analysis to evaluate the efficacy and safety of ACE for depression. Methods: Electronic searches will be conducted in 12 databases (both in English and Chinese databases), encompassing from inception to April 2022, without language restrictions. Randomized controlled trials (RCTs) that involve ACE for treating depression will be included. The primary outcome measures will include the response rate, Hamilton Depression Rating Scale (HAMD), Beck Depression Inventory (BDI), and Traditional Chinese Medicine Symptom Scale (TCMSSS). The secondary outcome measure will include Quality of Life scale score (QoL) and the incidence of adverse events. Results will be presented as risk ratios for dichotomous data and mean differences for continuous data. Two reviewers will independently conduct study selection, data extraction, and quality assessment. The methodological quality of eligible studies will be evaluated according to the criteria specified by the Cochrane Handbook for Systematic Reviews of Interventions (Version 5.1.0). Meta-analysis will be performed by RevMan 5.3 software. Discussion: Due to the limitations, a safer, high-efficacy and non-pharmacological intervention with minimal side effects is required for treating depression. ACE has the advantages of longer-lasting effects, improved patient compliance, and reduced treatment costs. This protocol represents a meta-analysis and systematic review, aiming to present the current evidence regarding the efficacy and safety of ACE for depression. It seeks to provide clinicians with a theoretical basis and valuable references for complementary and alternative medicine therapies in their treatment approaches.

RESUMEN
OBJECTIVE: To evaluate the clinical effectiveness and safety of acupoint catgut embedding and acupuncture on simple obesity by Meta-analysis. METHODS: Studies on clinical randomized controlled trials of acupoint catgut embedding for simple obesity which were published from January 2015 to November 2020 were searched in Cochrane Central Register of Control Trials (Central), PubMed, China Science and Technology Journal Database, China National Knowledge Infrastructure Database and Wanfang data-bases. And those that met the inclusion criteria were screened. RevMan5.3 was used for Meta-analysis. The "Risk of Bias" tool was used to evaluate the quality of included studies. R studio software was used for the measurement of publication bias. RESULTS: A total of 33 studies were included for Meta-analysis, including 2685 patients with simple obesity. Meta-analysis results showed the comparison of effectiveness rate was relative risk () = 1.12, 95%(1.08, 1.16), body mass index (BMI) was mean difference () = -1.12, 95% (-2.09, -0.14), waist circumference was = -2.14, 95% (-4.22, -0.06), and body mass was = -2.36, 95% (-3.99, -0.73). On the basis of diet and exercise intervention, the effectiveness rate [ = 1.12, 95% (1.05, 1.19)], BMI [ = -0.88, 95% (-1.35, -0.40)], waist circumference [ = -1.10, 95%(-4.27, 2.07)], and body mass [ = -0.68, 95%(-2.90, 1.54)]. The risk of bias of included literatures was low. CONCLUSIONS: Acupoint catgut embedding therapy was slightly better than acupuncture therapy in most of the outcomes. Moreover, the treatment frequency of acupoint catgut embedding is less with larger stimulation intensity, which is more conducive to clinical promotion.

OBJECTIVE: To systematically review and analyze the effect of acupuncture and acupoint catgut embedding in treatment of abdominal obesity to provide a more reasonable clinical treatment regimen. METHODS: Ten databases were searched as of August 2022: the English databases PubMed, Embase, Cochrane Library, Web of Science, Wiley, and Scopus and the Chinese databases China National Knowledge Infrastructure Database, China Science and Technology Journal Database, Wanfang, and SinoMed/Chinese Biomedical Literature Database. Randomized controlled trials (RCTs) of acupuncture and acupoint catgut embedding as the main interventions to treat abdominal obesity were extracted. The investigators imported the citations into EndNote version X9.1 for deduplication, screening, extraction, and integration. The risk of bias in the included RCTs was assessed according to the Cochrane Handbook. RevMan 5.4 software was used to conduct a Meta-analysis of RCTs that met the inclusion criteria. RESULTS: Thirteen RCTs (1069 patients) were included in this study, and the data of eleven RCTs (966 patients) were include in the Meta-analysis. The results showed that acupoint catgut embedding can significantly change the weight and waist circumference of patients with abdominal obesity when compared to sham acupuncture or no treatment [mean difference () = 2.32, 95% confidence interval () (1.88, 2.76), < 0.000 01], [ = 3.47, 95% (1.99, 4.94), < 0.000 01]. The change in hip circumference after acupuncture was also significant [ = 0.89, 95% (0.12, 1.66), = 0.02]. CONCLUSION: This study found that acupuncture and acupoint catgut embedding can effectively treat abdominal obesity, therefore, these interventions can be used as clinical supplements and alternative therapies. The diagnostic criteria of the existing studies and the intervention measures of the control group are not unified. It will be necessary to improve the clinical study protocols and expand the sample size to further validate the reliability of the results obtained of this study.

OBJECTIVE: To analyze the characteristics of acupoint catgut embedding methods, tools, catgut types, and the treatment cycles in the clinical research in recent ten years both at home and abroad, so as to summarize its regularities and to provide technical references for further studies. METHODS: Articles about clinical researches on catgut embedding therapy published in recent ten years (from January 1, 2010 to December 31,2020) were retrieved from the databases of CNKI, Wanfang, VIP, and PubMed by using key words of "acupoint embedding" "acupoint catgut embedding" and "catgut implantation at acupoint". According to the inclusion and exclusion criteria, a new database was established for analyzing the data mentioned above. RESULTS: 1) A total of 1 196 articles were collected, including 15 English articles and 1 181 Chinese articles, presenting a fluctuating increasing trend in recent ten years. 2) The commonly used acupoint embedding methods included disposable catgut embedment needle method (399 times, 38.89%) and disposable syringe needle catgut embedding method (347 times, 33.82%), for which two or multiple methods were mentioned in the same one article. 3) The most frequently used top two tools for catgut embedding were the dispo-sable catgut embedment needle (463 times, 43.03%) and disposable syringe needle (406 times,37.73%), with a significant increase in the application of disposable syringe needle. The most commonly used size of tools included No. 7 (283 times, 39.86%), No. 9 (196 times, 27.61%) and No. 8 (109 times, 15.35%). 4) The most frequently implanted surgical suture was still the common catgut (671 times, 58.15%) despite of a reduction in clinical application year by year, and the types of the implanted suture materials were gradually enriched since 2018, such as the absorbable surgical suture, polyethylprolactide(PGLA), collagen protein thread, polydioxanone(PPDO), etc. The commonly used implanted catgut size was 3-0 (227 times, 30.15%), 2-0 (176 times, 23.37%), 4-0 (131 times, 17.40%), 0 (103 times, 13.68%), with the commonly used catgut length being 1 cm (332 times, 35.55%), 1.5 cm (103 times, 11.03%), 1-2 cm (92 times, 9.85%) and 2 cm (92 times, 9.85%). 5) The intervals of the catgut implantation were 7 days (313 times, 28.95%), 14 days (262 times, 24.24%), 10 days (174 times, 16.10%), and 15 days (162 times, 14.99%). CONCLUSION: In recent ten years, clinical research on acupoint catgut embedding is growing rapidly, and the embedding methods, tools, implanted sutures, and embedding intervals are various, which may provide certain technical references for the future researches and suggest an urgent need of formulation of the standardized and unified standards in this field.

OBJECTIVE: To observe the effect of moxibustion combined with acupoint catgut embedding on the content of interleukin 6 (IL-6), and the expressions of janus activated kinase (JAK), signal transducer and activator of transcription 3 (STAT3) in colonic mucosa of rats with ulcerative colitis (UC), so as to explore its mechanism underlying improvement of UC. METHODS: Thirty SD rats were randomly divided into normal, model, acupoint catgut embedding (ACE), moxibustion and acupoint catgut embedding combined with moxibustion (combination) groups (n=6 rats in each group). The UC model was established by enema of trinitro-benzene-sulfonic acid and ethanol. Moxibustion was applied to bilateral "Tianshu" (ST25), "Dachangshu" (BL25) and "Shangjuxu" (ST37) for 10 min, once daily for 14 days, and ACE applied to the same 3 acupoints, once a week for two weeks. After the treatment, colonic mucosal pathological changes were observed by H.E. staining, the level of IL-6 in colonic mucosa was assayed by ELISA, and the expressions of JAK and STAT3 in colonic mucosa were detected by immunohistochemistry and Western blot. RESULTS: H.E. staining showed severe defect of the colonic mucosal epithelium with infiltration of a large number of inflammatory cells in the model group, which was milder in moxibustion, ACE and combination groups. After modeling, the content of colonic IL-6, and the expression levels of JAK and STAT3 were obviously increased (P<0.01) in the model group relevant to the normal group. Following the intervention, the increase of IL-6 contents, and JAK and STAT3 expressions were reversed (P<0.05, P<0.01) in moxibustion, ACE and combination groups. The therapeutic effects of moxibustion combined with ACE were considerably superior to those of simple ACE and simple moxibustion in down-regulating the levels of JAK and STAT3 expression (P<0.01). CONCLUSION: Acupoint catgut embedding combined with moxibustion can repair the injured colonic mucosa of UC rats, which may be related with its effect in suppressing the activation of IL-6/JAK/STAT3 signaling pathway.

OBJECTIVE: To evaluate the clinical effects of acupoint catgut embedding combined with quadruple therapy on Helicobacter pylori (Hp)-positive (+) chronic atrophic gastritis (CAG) of spleen and stomach deficiency syndrome and explore the underlying mechanism. METHODS: Hp (+) CAG patients with spleen and stomach deficiency syndrome were randomly divi-ded into a control group (n=68) and a treatment group (n=71). In addition to the routine quadruple therapy for two weeks, the patients in the control group received oral Weifuchun Tablets (4 tablets once, tid.), and those in the treatment group underwent acupoint catgut embedding at Pishu (BL20), Weishu (BL21), Zhongwan (CV12), and Zusanli (ST36), once a week. The two groups were treated for three months in total. The scores of traditional Chinese medicine (TCM) symptoms and signs, clinical efficacies, quality of life scale scores (PRO scores and HAMA scores), endoscopic and histopathologic scores, Hp eradication rates detected by 13C breath test, and the recurrence rates after six months of the two group were compared. The changes in serum gastrin 17 (G-17), pepsinogen â (PGâ ) and pepsinogen â ¡ (PGâ ¡) were detected by ELISA, and PGâ /PGâ ¡ was calculated. RESULTS: There was no significant difference in the eradication rate of Hp between the two groups after treatment (P>0.05), but the recurrence rate after six months in the treatment group was lower than that of the control group (P<0.05). After treatment, the scores of TCM symptoms and signs, endoscopic and histopathologic scores, PRO scores, and HAMA scores were decreased in both groups (P<0.01), while serum levels of G-17, PG â , PG â ¡, and PG â /PG â ¡ were increased (P<0.05, P<0.01). The treatment group was superior to the control group in alleviating stomach discomfort by pressing or warmth, decreasing the total score of TCM symptoms and signs, relieving anorexia, mottled gastric mucosa, mucosal ulcer, chronic inflammation, and activity, improving anxiety, and regulating G-17 (P<0.05, P<0.01). The effective rates of the treatment group and the control group were 40.85% (29/71) and 23.53% (16/68)ï¼the treatment group was higher than the control group (P<0.05). CONCLUSION: Acupoint catgut embedding combined with quadruple therapy in the treatment of Hp (+) CAG of spleen and stomach deficiency syndrome is significant in clinical efficacy and low in recurrence rate, which is presumedly achieved by repairing gastric mucosa and sensitizing the secretion of G-17 and pepsinogen.

OBJECTIVE: To systematically review the occurrence of adverse events/adverse reactions (AEs/ARs) induced by acupoint catgut embedding therapy for psoriasis vulgaris (PV) and its safety. METHODS: Randomized controlled trials, controlled clinical trials, cohort studies, case-control studies, case-series, and case reports concerning the treatment of PV with acupoint catgut embedding therapy were searched from Chinese and English databases from their inception to January 7th, 2021. The AEs/ARs related to acupoint catgut embedding therapy for PV were subjected to descriptive statistics, followed by the analysis of possible reasons. RESULTS: Finally, 16 studies were included, involving 1 158 patients. A total of 79 cases were reported to present with mild to moderate AEs/ARs related to acupoint catgut embedding therapy for PV, and there were no serious AEs/ARs or death cases. The most common AEs/ARs were local redness, swelling, heat, and pain (31.65%,25/79), followed by low-grade fever and fatigue (29.11%,23/79), isomorphic reaction (16.46%,13/79), local induration (13.92%,11/79), and fainting (8.86%,7/79). In terms of embedding materials, catgut (93.67%,74/79) and lumbar puncture needles or other puncture needles (49.37%,39/79) were proved the most common AEs/ARs-inducing factors. The proportion of AEs/ARs resulting from treatment interval≤two weeks (67.09%,53/79) and treatment course≤eight weeks (55.70%,44/79) was relatively high. Because the incidence of AEs/ARs fails to be calcula-ted, it is not yet possible to accurately assess the risk and safety of acupoint catgut embedding therapy for PV. CONCLUSION: Available evidence suggests that in the treatment of PV, acupoint catgut embedding therapy may induce a series of mild to moderate AEs/ARs, so its clinical practice deserves attention. We should strictly grasp its indications and contraindications, and prevent the occurrence of related AEs/ARs by standardizing the operation and improving the embedding materials.

OBJECTIVE: To observe the effect of acupoint catgut embedment(ACE) on expression of p38 mitogen activated protein kinase (p38MAPK), intercellular adhesion molecule-1(ICAM-1), interleukin-4 (IL-4) and eosinophils (EOS) in lung tissue of asthmatic rats, so as to explore its mechanism underlying improvement of asthma. METHODS: Forty male Wistar rats were randomly divided into control, model, ACE and dexamethasone (DEX) groups, with 10 rats in each group. The asthmatic model was established by intraperitoneal injection of mixture suspension (1 mL) of ovalbumin (OVA,10%) and 10% Al (OH)3+ normal saline, followed by inhalation of atomized 1% OVA solution for 30 min, once daily for 2 weeks to trigger occurrence of asthmatic symptoms. The ACE was applied once to "Feishu" (BL13), "Dingchuan" (EX-B1) and "Danzhong" (CV17). Rats of the DEX group were given intraperitoneal injection of DEX once a day for 2 weeks. H.E. staining was used to evaluate histopathological changes of the lung tissue. The relative number of EOS in the bronchoalveolar lavage fluid (BALF) was detected by Wright Giemsa staining. The apoptosis level of EOS in the lung tissue was detected by TUNEL staining. The ultrastructural changes of EOS in the lung tissues were observed by transmission electron microscope (TEM). The expression of p38MAPK, ICAM-1 and IL-4 mRNAs in the lung tissue was detected by quantitative real-time PCR. RESULTS: Findings of optical microscope and TEM showed obvious bronchial deformation and inflammatory cell infiltration, rupture of EOS cell membrane, uneven cytoplasm with swelling and uneven density of eosinophilic granules in EOS of the model group, which was relatively milder in the ACE and DEX groups. Compared with the control group, the EOS number in BALF and the expressions of p38MAPK, ICAM-1 and IL-4 mRNAs in the lung tissue were significantly increased (P<0.01), and the apoptosis index of EOS in the lung tissue was significantly decreased (P<0.01) in the model group. After intervention, the EOS number in BALF and expression levels of p38MAPK, ICAM-1 and IL-4 mRNAs in the lung tissue of ACE and DEX groups were significantly decreased (P<0.01, P<0.05), as well as the apoptosis index of EOS in the lung tissue was significantly increased in both ACE and DEX groups (P<0.01) in comparison with the model group. The EOS number in BALF and expression of ICAM-1 mRNA were significantly lower in the DEX group than those in the ACE group (P<0.05). CONCLUSION: Catgut embedding at acupoints may alleviate the airway inflammatory response in asthma rats, which may be related with its effects in down-regulating p38MAPK signaling, ICAM-1 and IL-4 mRNA expression, reducing the aggregation of EOS, and promoting the apoptosis of EOS.
